Still Grading... And Worse

My deadline is tomorrow. A handful of students still haven't handed in final papers, however I badger, pressure, and cajole. This is more upsetting than I can possibly say. Students who could do well, who have been doing reasonably well so far, who have certainly been passing at any rate, are going to fail -- and there is little I can do about it. I know I may seem to complain about the excruciating intensity of final grading, but far worse still is waiting for work to grade that never comes...
